c. Migration distance on a gel is inversely proportional to DNA fragment size

Explanation:

Deoxyribonucleic acid is a genetic material that is a type of macromolecule. It is made up of a monomer that ais called a nucleotide. Each nucleotide is made up of a deoxyribose sugar, a base, and a phosphate group. Due to the presence of phosphate group DNA has negative property. When the DNA is separated by the gel electrophoresis method the size of the fragment of the DNA plays an important role. Those DNA fragments that are small in size migrate faster than those DNA fragments that are larger in size. So the migration distance is inversely proportional to the DNA fragment size.
